If you are seeking intensely powerful sub-bass that compromises
nothing in terms of sound quality, the 12W6v3 is your ultimate ally.
This highly advanced subwoofer driver offers several technologies shared
with the flagship W7AE subwoofers to provide powerful advantages in
motor linearity and suspension behavior. These combine with a very
efficient cooling circuit to deliver reduced distortion and outstanding
dynamic balance.

The 12W6v3 is best used with amplifier power in
the 200W - 600W range and is optimized to operate in a sealed enclosure
with only 1.0 cu. ft. (28.3 l) of air space, or a 1.3 cu. ft (36.8 l)
ported enclosure. Detailed enclosure recommendations can be found in the
Specifications tab.
